Barbie's Family

This article is a categoric listing of the names of the extended friends and family characters that have been merchandised for the iconic Barbie doll during her decades-long career as the world's most famous fashion doll. This is a chronological listing, featuring issue dates for the first year of release for a given character doll, and an end date where applicable. Names can be and often are re-used by Mattel, sometimes with spelling differences, which has led to two or more different characters having the same name, often at or around the same time frame.
